What OSI physical layer term describes the physical medium that uses the propagation of light? Group of answer choicesfiber-optic cablelatencygoodputthroughput

Identification of the Correct Term

In the context of the OSI (Open Systems Interconnection) model, the physical layer refers to the physical medium used for communication between devices. The question specifically asks for the term that describes a physical medium which relies on light for data transmission.

1. Options Analysis:

   • Fiber-optic cable: This type of cable transmits data as pulses of light through glass or plastic fibers.
   • Latency: Refers to the delay before a transfer of data begins following an instruction for its transmittal.
   • Goodput: This is the measure of useful transmitted data over a network.
   • Throughput: This indicates the rate at which data is successfully transmitted over a network.

2. Conclusion: Among the provided options, the term that correctly describes the physical medium that uses the propagation of light is fiber-optic cable.

Final Answer

The correct term is fiber-optic cable.
